Tolerances:You can find information about tolerances for our springs if you follow this link.

Max. working temperature:EN 10270-1 = 120 °C

Springs with Dt ≤ 0.4 do not have ground end coils, others have 3/4 end coils ground. Springs with Dt ≥ 2.0 are shot peened. Static loaded springs or springs with a low number of intended load deflections can be allowed to be scragged to solid length (Lst). A certain relaxation (load loss) will then appear.
